This invention relates to coin controlled feed means-for counting orother machines 1 n which the counting or other mechanism is coupled foractuation to the feed mechanism by means of the coins. Hitherto thecoins have been passed for this purpose through a channel in one end ofwhich a pawl coacting with a ratchet wheel engages and which is forcedout of the channel by the aid of the l coin. As there are coins ofvarious sizes and thicknesses a separate guide channel had to beprovided for each kind of coin so as to obtain the same degrees ofangular movement of the pawl. This disadvantage is-overcome by thepresent invention and means for operating the ratchet wheel are providedwhich suits all kinds of coins.

According to the present .invention the coins are fed through themachine by two opposed rollers which are connected one with the other bya gear and revolve .in opposite directions, transmitting theirperipheral motion to a coin engaged with a peripherally recessed discconnected with means for controlling the coin-feeding, and for varyingand limiting the quantities of coins.

One form of the invention is illustrated in the accompanying drawings,in which Figure 1 is a view of the apparatus from above.

Figure 2 is a section on the line I-I of FiO'. 1 and Figure 3 is asection on the line II--II of Fi l.

Fig. 4 is a detail horizontal section on line 4-4 of Fig. 5, and

Fig. 5 is a section on line 5 5 of Fig. 4. The coins 1 to be countedpass out of the receptacle in which they have been collected or thedistributing chamber through a mouth piece 2. Beneath this mouthpiece 2are arranged rollers 3 and 4 on parallel shafts 5 and 6 respectively insuch a way that these rollers are situated opposite each other in thedirection of their diameters and a narrow slit 7 is left between theexternal surfaces of their peripheries, into which the coin l emerginfrom the mouth piece 2 drops.

he coin 1 gripped between the rollers 3 l0 and 4 in the slit 7 engagespartially in one of ten recesses 8 in the periphery of a disc 9, whichis carried on the driving shaft 10 of a counting or dispensing mechanism(not shown The walls of said recesses are forme as cams. Opposite thedisc 9 a guide roller 11 for the coin 1 is mounted to rotate loosely ona lever 13 pivotally mounted at 12. This coin denomination selectorlever 13 is provided with a handle 14 and a pin 15 which can be causedto engage in a hole 16 in a stationary plate 17 so as to enable theguide roller 11 to be held in a definite position corresponding to thesize of the coin. A number of holes 16 are arranged in stages in theplate 17 to correspond to the various kinds of coins. l

In order to enable the distance between the rollers 3 and 4 to beregulated to correspond to the thicknesses of the coins the shaft 5 ofthe roller 3 is mounted in adjustable bearings 18 and 19. As shown inFig. 4 the bearings 21 and 21 are fixed on a base plate 48 or the like.Bearing 19 is rotatable around pivot 23 of plate 48. Bearing 18 is dilaceably mounted in sl'ot 49 of plate 48. pring 2O serves to keepbearing 18 apart from bearing 21 and to press it against regulatingscrew 22. Screw 22 regulates the distance between bearings 2l and 18 andconsequently the distance between rollers 3 and 4. By this 50 means ofhaving the spring press the rollers apart instead of toward each other,and regulating by the adjustment of the screw 22 the spacing of therollers, the rollers are prevented from engaging and advancing coinswhich are worntoo thin, and if a coin which is too thin gets between therollers the machine stops, thereby enabling the person operating themachine to recover the faulty coin. The bearing 18 is actuated byv aspring 20 which tends to move the bearing 18 away from the bearing 21 onthe shaft 6. The movement of the bearing 18 is limited by means of aset' screw 22 arranged in a screwthreaded hole of a vertical stationarywall to form an adjustable stop encountered by said bearing 18. 'Iheshafts 5 and 6 are connected together by toothed wheels 24 and 25 andare driven at the same speed by means of the bevel wheels 26' and 27 Ina recess `8 in the disc 9 is engaged a roller 30 which is mounted on onearm of a two-armed lever 29 pivotally mounted at 29 and loaded by aspring 28 to control the movement of said disc 9. 0n the other arm ofthis lever 29 is mounted a pawl 31 which engages in a. ratchet andlocking wheel 32 rigidly connected to the disc 9. Star wheel 9 is movedby a coin (the latter being moved by rollers 3, 4) at a certain anglecontrolled by roller 30. Roller 30, during this turning action, passesover a cam positioned between two recesses 8 and turns lever 29 insuchmanner that part 31 of the lever follows and touches a tooth of wheel32, cooperating with lever 29. The pressure exercised by toothed-wheel 9upon roller 30 and lever 29 is thus transferred back, by means of wheel32, to star wheel 9, and is used at the same time, and in addition tothe driving force of the pressure of the coin, for turning the toothedwheel. Thus lever 29 engaging in the recesses 8 of the counting wheel 9exercises, when actuated by the coins, resistance upon the countingwheel. This resistance is reduced by the action of the auxiliary pawlwhich engages in ratchet wheel 32, when the roller passes the tooth ofthe counting wheel, and thereby helps to overcome the resistance whichroller 30 encounters on the tooth.

Connected to the disc 9 by the shaft 10 is a gear wheel 33 which engagesin a ear wheel 35 provided with a pin 34. e

pin 34 strikes at each revolution of the gear I wheel 33 against one armof a star wheel 36. (see Figure 3) and rotates h this latter through afixed angle. The star wheel 36 is provided with laterally projectingpins 37 in the path of which an' arm 38 of a pawl 40 pivotall mounted at39 projects while the tooth 41 o the pawl 40 engages in a notch 42 in alongitudinally movable rod 43 under the action of a spring 44 andthereby holds the rod 43 in its initial position. This rod 43 isactuated by a spring 45 which when the tooth 40 of the pawl is releasedfrom the notch 41 thrusts the rod 42 so far forwards that its front end46 projects into the mouth piece 2 and thereby prevents coins fromissuing from the mouth piece as shown Ain Figure 2.

The rollers 3 and 4 which rotate at thel same speed and in oppositedirections grasp one coin after another and force each coin into'arecess 8 of the disc 9 thereby clearing the propelled coins of anyinjurious frictional connection. The coin 1 entering a recess 8transmits the peripheral force of the rollers 3 and 4 to the disc 9until it has passed these rollers and the recess 8. Between the rollers3 and 4 and the disc 9 the coin produces a kinetic connection wherebythe disc 9 is rotated through a definite angle. At the same time thelocking roller 30 of the lever 29 will leave the recess and pass overmits one and the Vsame isc to be used for all the kinds of coins thatmay occur.

After a certain quantity of coins have beenpassed the disc 9 the machineis stopped When for example the hundredth coin passes in contact withthe disc 9 a pin 37 on the star 36 strikes against the arm 38 of thepawl 40.

To reset ing locking bar 43 is retracted to the right (looking at Fig.3), until the springpressed pawl 40 engages the groove 42 to kee thelocking bar 43 in its initial position w ereupon the prescribedoperations are repeated. i
